AXLE-BOX GAGE.

SPECIFICATION forming part of Letters Patent No. 253,823, dated February 14, 1882.

Application filed December 9, 1881. (No model.)

To all whom tt may concern: Be it known that I, JOHN A. MYERS, a citizen of the United States, residing at Monroe City, Lovely Dale, in the county of Knox and State of Indiana, have invented certain new and useful Improvements in Setting Boxes in Wagon or Carriage Wheels, of which the fol: lowing is a specification, reference being bad therein to the accompanying drawings.

My invention relates to devices for setting hub-boxes; and it consists in the construction and arrangement of its several parts, as will be hereinafter fully set forth.

In the drawings, Figure 1 is a top plan view; and Fig. 2 is a view partly in section, and showing a side elevation of my device.

A is a wheel of ordinary construction, of which a is the hub, a the spokes, and a the felly.

B is aplug orspindle which tits the hub-box. It may be made tapering to vfit hub-boxes of difl'erent sizes, or straight, and different sizes of the plug made to lit thevarious sizes of hub boxes.

O is the gage arm. It has a sot, c. by which idly in place against the spindle, or by loosening them the outer end of the gage-arm can be set at different distances from the center to correspond with the diameter of the wheel.

E is an iudex rod. It passes through a threaded hole in the outer end of the gagearm, and is provided with a lock-nut, e, by which it may be rigidly fixed upon the gagearm.

' The operation of the device is readily understood. By setting the gage-arm and its index-rod so that the latter reaches the outer edge of the felly, and by then moving the index-points around to different points in the circumference of the wheel it can be determined when the box is accurately centered in grhe hub.

What 1 claim is- The combination of the spindle B, gage 0, nuts 61, and washer d with the index-rod E, operating in a threaded hole in the outer end of thegage-arm,,and provided with a locknut, e, and with the wheel A, substantially as shown and described.

In testimony whereof [affix my signature in presence of two witnesses.

, JOHN ALVIN MYERS.
